Hello Guix, When running ‘guix pull’ with the --system flag the resulting guix is configured for the host architecture instead of the target architecture (i.e. the %system variable in ‘(guix config)’ is set to the host architecture instead of the target architecture).
E.g. after running ‘guix pull -p test -s i686-linux’ on an x86_64 host the file test/share/guile/site/2.2/guix/config.scm will contain the declaration ‘(define-public %system "x86_64-linux")’. I run what was formerly known as GuixSD (commit: 571a01d) on x86_64. Regards, Diego
